gcc: Add target gcc include search for musl config too

Musl has different search order and therefore injects it
via INCLUDE_DEFAULTS and does not use the defaults from
gcc/cppdefaults.h, this ensures that same fix is extended
to musl configs too where it can search for compiler headers
It will fix builds with musl where omp.h is not found because
it is in gcc includes path on target ( not cross ) sysroot
